These devices consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships. https://elecena.pl/product/9716314/lm393drg4-comparator-dual-soic-8 2017-08-06 https://elecena.pl/product/9716314/lm393drg4-comparator-dual-soic-8 2018-05-04 https://elecena.pl/product/9716314/lm393drg4-comparator-dual-soic-8 2018-12-17 https://elecena.pl/product/9716314/lm393drg4-comparator-dual-soic-8 2019-06-21 https://elecena.pl/product/9716314/lm393drg4-comparator-dual-soic-8 2021-04-25 https://elecena.pl/product/9716314/lm393drg4-comparator-dual-soic-8 2022-01-30 https://elecena.pl/product/9716314/lm393drg4-comparator-dual-soic-8 2023-04-24 https://elecena.pl/product/9716314/lm393drg4-comparator-dual-soic-8 2026-01-07 https://elecena.pl/product/9716314/lm393drg4-comparator-dual-soic-8 2026-02-04
